Effects of Deep Tillage and Straw Returning on Soil Microorganism and Enzyme Activities

open access: yesThe Scientific World Journal, 2014
Two field experiments were conducted for two years with the aim of studying the effects of deep tillage and straw returning on soil microorganism and enzyme activity in clay and loam soil.

Critical limits of soil penetration resistance in a rhodic Eutrudox

open access: yesRevista Brasileira de Ciência do Solo, 2014
Soil penetration resistance is an important indicator of soil physical quality and the critical limit of 2 MPa has been widely used to characterize the soil physical quality, in both no-tillage and conventional systems.

Cover Crop Termination & Reduced Tillage Study [PDF]

open access: yes, 2012
When a crop such as corn silage is harvested in the fall, the entire plant is removed leaving the soil exposed through the winter. These exposed soils are more prone to run-off and erosion of sediment and nutrients into surface waters.

Abiotic pulses and microbial activity lags in greenhouse gas emissions due to tillage

open access: yesAgrosystems, Geosciences & Environment, 2020
Tillage affects atmosphere–soil greenhouse gas (GHG) flux by opening soil pore spaces releasing pockets of CO2, CH4, and N2O. Tillage may also stimulate microbes responsible for GHG biogenesis and consumption at longer time scales following a discrete ...

Effects of no-tillage and subsoil loosening on soil physical properties and crop performance : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Soil Science at Massey University [PDF]

open access: yes, 1998
Much of New Zealand's lowland agriculture integrates animal and crop production on poorly drained, easily compacted soils. Over the years, conventional cultivation has given rise to degraded soil structure on many farms.

Effect of Tillage Practices on Soil Properties and Crop Productivity in Wheat-Mungbean-Rice Cropping System under Subtropical Climatic Conditions

open access: yesThe Scientific World Journal, 2014
This study was conducted to know cropping cycles required to improve OM status in soil and to investigate the effects of medium-term tillage practices on soil properties and crop yields in Grey Terrace soil of Bangladesh under wheat-mungbean-T.

Mulching and soil tillage influence on the thermal behaviour of a Luvisol surface layer [PDF]

open access: yes, 2009
Important energy exchanges at soil surface regulate the thermal environment within top soil layer and the boundary layer above it. By this reason, the application of mulches or the modelling of micro relief by soil tillage are common practises to modify ...
